Production description
Hot-dip galvanized carbon steel hexagonal nuts, nuts are nuts, with bolts or screws screwed together to play the role of fastening parts, all manufacturing machinery must use an original. There are many kinds of nuts, we often have national standard, Standard, n Standard, Japanese standard nuts. Nuts according to different materials, divided into carbon steel, high-strength, stainless steel, plastic steel and other major types. According to the product attribute corresponding to the different national standard number is divided into ordinary, non-standard, national standard, new National Standard, n system, system, German standard. Threads of different sizes are not equally divided into different specifications. General National Standard, German standard with M, n system, system with scores or specifications.
Nuts are mechanical equipment closely connected parts, through the inside of the thread, the same size nuts and screws, can be connected together, such as M4-0.7 nuts and M4-0.7 only with the screw; The same is true for N products, such as 1/4 -20 nuts only with 1/4 -20 screws. At present, Hebei PU in Yongnian County, the largest distribution center for nut production in China, is affordable and the local logistics are accessible, but high-precision, high-tech nuts are most reliable in some southern cities.
Such as the Guangdong area of Zhuhai Zino energy-saving Equipment Co. , Ltd. is specialized in the production of various copper accessories. Nuts commonly used national standard GB41I type hexagonal nuts-c type hexagonal nuts-a, B type hexagonal nuts-fine pitch a, B type hexagonal thin nuts-a, B type hexagonal thin nuts-chamfer GB6173 hexagonal thin nuts-fine pitch a, B type GB6174 hexagonal thin nuts-b type hexagonal nuts-no chamfer GB6175II.
